When my bike is still, and I firmly squeeze the front brake lever, it feels like it is binding or sticking as it is squeezed towards the lever..... in steps.
Is this a sticking master cylinder piston ? ( seal swell or warn piston ?)
No leaks and the brake seems to have proper strength.
OK, new update. As I squeezed the lever and stooped down next to the right front caliper, I heard the caliper actually clicking as I squeezed slowly on the lever. The caliper was actually making a clicking sound with a vibration with each click.
The caliper completely releases when I let up on the lever, no leaks and has proper strength. Only does this when squeezing lever slowly and firmly..... normal ?
So I took that caliper off the bike completely cleaned it checked it over and it looks absolutely perfect. lubed up the brake pad mounting pens after sanding them with 800 grit sandpaper. Put it all back together and squeeze the lever some more and look everything over once again. It is making this sound louder by The master cylinder itself so it is probably the piston that is dragging in there.
My front brake lever would not pull smoothly through its travel, so I pulled the lever cleaned the brass bushing it with my pistol cleaning wire brush, cleaned the entire area with basic cleaning stuff, put white lithium grease on every metal to metal contact point. It's so smooth now I can hardly tell I have actually pulled it in.
